I guess I wasn't staying still enough the first two times because the Sentinel lab contacted me and said my impression was distorted. I stayed perfectly still the third time and made sure I waited the full three minutes before I removed the tray. Scared me for a brief second because the putty was so hard I thought it was going to pull my teeth out!! But it came out just fine and I got a great fitting nighttime guard. Thank you for working with me :D

Love my guard! Easy to use at home kit. I've sent several people your way since I received my dental guard. THank you!

Great company to work with. They'll make sure your guard fits right, and there is a real person on the other end of the phone.

We love this service. My wife and I both use the Sentinel night guards because they're very comfortable, affordable and now that the Sentinel lab has our dental impressions on file we can order future guards with ease if we grind through these!

Very impressed with this product! I ordered the Sentinel nightguard to replace an older, worn down guard that I had gotten from my dentist about 15 years ago. I was skeptical that it would be the same as the one I had gotten originally. It is much more comfortable than my dentist made one. Less bulky. I don't know if it'll last 15 years but at this price I'll take it!

Love everything about my new Sentinel night guard!

Bought this for my daughter. She said on a scale of 1 to 10 it is a 10 in comfort! She's been a longtime teeth grinder. The dentist said she would grow out of it as a child but here she is at 18 still doing it. We have tried the walmart guards and they never were comfortable enough for her to wear during sleep. Truly the best! We looked around and decided on Sentinel. Glad we did. Thank you!

Well worth it!! Easy to follow directions. Great for both beginners and experienced dental night guard wearers. Only would have loved a faster turnaround time but I'm pleased with the final product. Now I can't wait until my nighttime grinding is cured so that I can quit sleeping with plastic in my mouth!!

I am a horrible nighttime teeth grinder and clencher. I have managed to chew threw so many of these things. I am very happy with this guard. I love that the company keeps impressions on file for 2 years because I don't enjoy taking my dental impressions and I may need another soon!

Not bulky. The fit is very nice. I have used this for 3 nights so far and I think this may be the best purchase I've ever made. I highly recommend this product for anyone who experiences pain from teeth grinding.
